> I have created a tool similar to the broker shutdown tool for doing rolling
> restarts of Kafka clusters.
> The tool watches the max replica lag of the specified broker, and waits until
> the lag drops to 0 before exiting.
> To do a rolling restart, here's the process we use:
> for (broker <- brokers) {
> run shutdown tool for broker
> terminate broker
> start new broker
> run wait for replication tool on new broker
> }
> Here's an example command line use:
> ./kafka-run-class.sh kafka.admin.WaitForReplication --zookeeper
> zk.host.com:2181 --num.retries 100 --retry.interval.ms 60000 --broker 0
